crc(spec[, tables = Multiple])

Create a crc function implementing spec with lookup table behaviour tables. Available specs are listed in ALL and tables can be either Multiple, Single or NoTables.

The returned function accepts String, Vector{UInt8} or IO and calculates the CRC checksum. An optional boolean parameter append can be used for chained application.

A faster CRC32C implementation is available in Stdlib: CRC32c.

Examples

using CRC

# create our own crc function, just once
crc32 = crc(CRC_32)

# use the crc function created above, many times
for s in ["hello", "there"]
    println(s => crc32(s))
end
